The National Monuments Service's description
A small circular island (diam. c. 15m) is shown on the 1838 OS 6-inch map in middle of an unnamed lake which straddles the townland boundary between Knockaunacat and Lisanny. It is not shown on later map editions where reduced lake levels are evident. Modern drainage schemes have reduced the lake to an expanse of marsh ground, too wet and unstable to allow inspection.
